ABSTRACT:
Metal values are recovered from ore concentrates by forming a sulfide matte, grinding the matte, leaching with sulfuric acid at elevated temperature to selectively extract nickel and iron, and leaching the residue with an acidic aqueous ferric or cupric salt to selectively extract copper. The residue contains a high concentration of platinum, palladium and gold.
